Hello,

I am trying to upgrade to the latest distribution of transformers (`4.9.1` according to [Release v4.9.1: Patch release · huggingface/transformers · GitHub](https://github.com/huggingface/transformers/releases/tag/v4.9.1)).

I currently have the version `4.3.3` installed and it works fine. So, I downloaded the 4.9.1 zip file, extracted to a directory, `cd` to that directory and run `python setup.py install`.

The install went fine (except for the `huggingface-hub` requirement at the end — which is blocked by my firewall). However, when I start spyder again the version is still `4.3.3`.

Am I doing something wrong to update the package offline (on windows)?  
Thanks!

I was able to upgrade by using `pip` instead. Weird that the good old `python setup.py install` would not work in this case.

I am trying to install transformers 4.9.1.  
I currently have 4.48.1.  
I tried with pip and with conda but tokenizer version is throwing error.  
It is looking for tokenizer 0.11 whereas I have tokenizer 0.21

My env has following package versions:

python 3.10  
torch 2.5.1  
pytorch-lightning 2.0.3  
pytorch-ingnite 0.5.1  
tensorboard 2.18

Looks like 4.9.1 is compatible with python 7!!

I will stick with the current version.  
Please close this question.  
Thanks for your help.

4.48.1 is the latest version of pip at the moment. 4.9.1 is a version from four years ago. Because 48 is greater than 9.
